Study Notes
DNA Repair Pathways
- Nucleotide Excision Repair (NER) is responsible for repairing external damage, such as UV damage.
- Recessively inherited defects in NER genes can cause Xeroderma Pigmentosum, a genetic disease.
- Base Excision Repair (BER) is responsible for repairing single strand breaks in DNA.
- Homologous Recombination (HR) repair pathway is responsible for repairing double strand breaks in DNA through the use of homologous sequences.
- Nucleotide Excision Repair (NER) is also responsible for removing damaged sections of DNA and filling the gap with DNA polymerase.
